CASING AND GUIDE FOR WINDOW-SHADES, ac-

Application filed November 17, 1909.

To all whom it may concern:

Be it known that I, MARY TV. CONWAY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Casings and Guides for Window-Shades, &c., of which the following is a specification.

My invention relates to devices for the protection and use of window shades, its object being to provide an article of convenient use in connection with the ordinary window-shades and the like, (such as maps, etc.) carried upon spring rollers, whereby they may be preserved and protected while in use and out of use from dust or other injury.

To this end my invention consists in a cylindrical casing, adapted to contain the spring roller commonly used with window curtains, and to engage the roller upon its projecting spindles, and thus completely incase the curtain.

The casing is provided with a longitudinal opening with a marginal curb wall extending outwardly, forming a guide to the curtain in winding on or off the roll. The inner surfaces of the curb wall may be provided with a covering of plush or other suitable material, to act as a brush and remove dust from the curtain on entering the casing; and the brace or rib attached to the lower edge .of the curtain to carry the operating ring,

forms a complete closure of the mouth of the curbed opening, when the curtain is out of use, to prevent the entrance of dust, etc. The casing thus completely covers and protects the curtain, its roller and winding mechanism, and also preserves a constant operative relation between the curtain and the winding spring of its roller; so that the usual annoyances of disarrangement are avoided.

lVhen entirely detached and stored away, the casing affords complete protection from light, insects, dust, etc.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my device complete and in position. Fig. 2, a perspective view of one end portion of the casing sectioned across to show the relation of the curtain roller thereto, and the relation of curtain to the guide opening and guide curb. Fig. 3, is a detail view of the same extreme end of the casing, showing the projection of Specification of Letters Patent.

the squared spindle of the curtain roller; and Figs. 4 and 5 are details of the opposite end-portion of the casing and of the end cover respectively, showing the extension feature.

Referring now to the drawings, A designates a cylindrical casing, preferably of sheet metal, of sufficient length to take in a curtain roller 1" of the ordinary type, having spring winding mechanism. The spindles, s 5 of the roller project through the ends of the casing-the squared spindle s of the roller spring mechanism projecting through a corresponding squared hole 8 in the casing, which prevents rotation and with which it thus cooperates in the same manner as with its normal supporting bracket 5 and also with the bracket 6 in retaining the casing A in normal relations with the curtain and the window frame. The casing A has a longitudinal opening at one side which is extended outward by a marginal curb (Z, forming parallel walls. Through the space thus inclosed, the curtain passes and is guided to proper seating on its roller 1. A rib c is attached to and across the free end of the curtain and is formed to seat upon or within the mouth of the exit opening of the curb (Z.

The curb wall (Z is preferably lined throughout by plush or similar material to sweep both sides of the curtain free of dust in entering.

The casing and guide may be made of lengths to fit the width of curtains according to the standard sizes commonly in use; but an extensible casing may be made by using a main cylinder A of minimum length, but with longitudinally extending curb walls (Z (Z which are to be shortened as far as may be necessary and the end of one bent over as shown in Fig. 4. The end cap, A has a slot a, at one side formed to inclose the extension curb outwardly and to slip over the cylinder A to placeas indicated in Fig. 1.

There is thus formed a complete casing which is practically an adjunct to the spring curtain-roller in common use, requiring no change whatever in the roller, or its brackets (and their mode and place of attachment), or in the curtain or its attachment to the roller; and which, when the curtain is wound on its roller to the highest limit, forms a dust proof protection and storage casing. It also, while in use, prevents the settling of dust upon the curtain at the top of the roller (a very common source of injury) and, besides, brushes off the dust at both sides of the curtain before it"passes into the casing and upon the roller.

The device, as will be obvious, can be used for maps, pictures, etc.

I claim as my invention and desire to secure by Letters Patent of the United States:

1. A casing for curtains consisting of a cylindrical covering pierced at its ends for the spindles of the curtain roller, and adapted to engage one of said spindles non-rotatively, having a longitudinal exit-opening provided With a curb-Wall constituting a Winding guide for the curtain; said curb- Wall being formed of substantially parallel oppositely projecting spaced members having a lining of cloth or similar material to brush dust from the sides of the curtain in entering.

2. A casing for spring roller Window shades consisting of a cylindrical covering closed at one end and pierced through its end Wall for the projection of one roller spindle, and having a longitudinal opening at one side provided With a curb Wall extending the opening outward, and extensions of said Wall beyond the open end of the casing, in combination With a shorter section of cylindrical casing closed at the outer end and pierced for the projection of the other spindle of the roller, slotted at one side and adapted to slip over and upon the main casing asan extension thereof.

In testimony whereof I have hereunto set my hand in presence of tWo subscribing Witnesses.
